NO video yet, just a log indicating something seen in a video.
"The document, if accurate, is either significant evidence kept secret for nine years or a misconstrued recounting of investigative leads that were often passed by word of mouth during the hectic early days of the case, they said."
Could this be the video that the log refers to?
"The only video prosecutors introduced at trial showed the Ryder truck without any visible passengers as it passed a security camera inside a high-rise apartment building a block away from the Murrah building."
It is possible that they extrapolated the info from the apartment building security video, knowing how long it would take to get into postion in front of the federal building from where it was seen in front of the apt. building.
"But the Secret Service log reported on April 24 and April 25, 1995, that there was security footage showing the Ryder truck pulling up to the Murrah building. The log does not say where such video came from or who possessed it.
A log entry on April 25 states that the security footage allowed agents to determine the time that elapsed between suspects leaving the truck and the explosion. "
The above, in bold, could just be a poorly worded way of refering to the apartment building video.
